Patent number: 6098728Abstract: A drillbit with a flexible nozzle system is provided to address bit- and bottom-balling situations. In one embodiment, a given nozzle can have an mounting member which is oblong or another shape so as to be installable into different positions where, in one position, the bit-balling problem is addressed, while in the other, the bottom-balling problem is addressed. Other shapes that provide this flexibility can also be employed. The nozzle body can also be made with a symmetrical mount, with the outlet askew such that the symmetrical mount, when placed in a strategically located nozzle opening, can address bit- or bottom-balling situations by a simple reversal of the orientation where multiple orientations are available for the base. Alternatively, in the area between adjacent cones, multiple nozzle installations can be provided to independently address the bit-balling and bottom-balling situations between adjacent cones.Type: GrantFiled: March 27, 1998Date of Patent: August 8, 2000Assignee: Baker Hughes IncorporatedInventors: Jennifer Ann Wells, Wayne Lee Baker, Christopher Steven Charles, James Lynn Duggan, Thomas John Gottschalk, Timothy King Marvel, Daniel Edward Ruff, Troy Richard Stuart

Patent number: 5922394Abstract: The present invention is directed to producing a luminescent screen used in a cathode ray tube (CRT) suitable for monochromatic or chromatic images, such as, those utilized in televisions, computers or data monitoring equipment, which require CRTs. The method of the present invention produces an ablative layer of the luminescent screen having a smooth surface with reduced surface distortions, such as, streaks and waviness, which are typically produced by conventional coating processes. When a reflective aluminum film is deposited on such a smooth ablative layer, the reflective aluminum film is also provided with a smooth surface, since it typically conforms to the underlying smooth surface of the ablative layer. As a result, CRT images having reduced distortions are produced.Type: GrantFiled: March 27, 1997Date of Patent: July 13, 1999Assignee: Rohm and Haas CompanyInventors: Andrew Paul Trapani, Gary Robert Larson, Steven Charles Brown, David William Whitman
